We have an MFI tester<\/strong> to ensure the quality of the raw materials during the incoming goods inspection.<\/p>\nThe melt flow index tester is the basis for characterizing thermoplastics during incoming inspection. The results of the measurements are a fingerprint<\/strong> for the behavior of the material during processing.<\/p>\nThe value determined is also a measure of the molecular weight<\/strong> and therefore an indication of the mechanical properties of the material. The average molecular weight and the result of the measurement are indirectly proportional.<\/p>\nThe MFI tester has further possibilities. For example, rheological data<\/strong> can be determined using tests with different weights. In addition, the die swelling behavior (“swell”)<\/strong> can also be determined. This is the arithmetic ratio between the cooled extrudate and the die diameter.<\/p>\n<\/div>\n<\/div>\n<\/div><\/div><\/div>![](\"https:\/\/www.hunold-knoop.de\/wp-content\/uploads\/ueber-uns\/qualitaetsmanagement\/mfi1.jpg\" "\\"mfi1\\"")
